To fill ic/wm 'z'tmay concern:

Be it known that- 1, ADAM vA. Loxo, of Rochester, in the county of .Monroe and State of New York, have invented certainnew and useful Improvements in Tire-Tools; and '1 do hereby declare the following to be a full, clean-and exact description of the same reference being had -Ito the accom-' panying di awings, forming'a part of this specification, and marked ,thereon. I r

a My present invent-ion relates to means for adjusting the tires of vehicle wheels, and it has for its object to provide a-devi'ce of this nature particularly adapted for use' in. ap- "plying the casings of pneumatic tires to their rims or' removing them therefrom which will greatly reduce the manual labor involved in these operations and allow a ,rapid i'nanipulation of the tire withoutsub jecting it to injury.

My improvements are fhrther directed torvard simplicity of construction and econonly of manufacture.

To these and other-ends the invention consists in certain improvements and cor'nbin'a tions of parts all as will be hereinafter more fully described; the novel features being pointed out in the claims at the endof the specification. In the-drawings: Figure Iis a side ele ration of a vehicle wheel withmy adjuster thereon in position for applying the outer edge of the tire to the rim. Fig. 2' is a top plan view of thetiie and r'im (if-a wheel with the adjusting shoe in the position it occupies when used in applying .the tire. l ig, is a similar viewwith the. adjusting shoe in position for removing the tire. Fig; -t is a perspective view of the adjusting shoe. Fig. 5 is a side View thereof. Fig, 0 is a transverse sectional view taken on the line ti-6 of Fig. 2, and Fig. 7 shows the blank from which the body portion of the shoe is formed. a e i 4 Similar reference figures indicate similar parts,

A device constructedxin accordancewith my invention is of particular value for use upon the pneumatic rubber tires of automobile wheels; which usually embody a strong outer casing of heavy and relatively stiff material having beads or flanges upon numerals in the several its edges adapted to bear against or engage beneath the .tlanges upon the rim of the wheel and inclosmg a soft inner tube, the

' beads being held clenched 'against the flanges by clamps or lugs or bv'the pressure produced through the intl'ati'on of the tire. The

frequency with which these tires become de flated either from punctures through the casing or by reason of the bursting of the inner tube through various causes; make it desirable that there he means convenient to the operator, whereby the outer bead, atleast. of the casing may be' quickly" and withdrawal of the inner tube for repairs,

. easily relnoved from the riim to .permit the and its replacement in its former position.

To these ends, I provide a device embodying generally a shoe of proper configuration.

which travels-upon the flange of the rim in contact with the head of the tire and forces the latter either on 01 oh at. the option of'theoperator, when rotated in the proper direc tion' throughout the circumference of the h" Prferably by means of an adjustable "i lever having a fulcrum bearing upon the hub of the latter.

, [Referring to the drawings l indicates a preferably sheet-metal shoe which maybe conveniently formed from a blank punched" as shown in Fig. 7, tl1e--o11terf.e(lge thereotbeing bent substantially at right angles to its face to form a guard 2 which extends at;

anangle to the opposite edge of the triangular bottom plate 3, comierging therewith at the narrower end of the latter,- where a downwaidly-projecting and slightly curved;

flange-4 is provided. At its opposite or broader extremity, the bottom plate "is profvided with a somewhat: similar .fiange 5. which, however, extends beyond' the. end.

thereof and substantially opposite a corre spending extension 6 of the guard 2, the said parts forming supports for the ends of a .pin'tle 7 extendingtransversely in alineriient with the bott'om plate. Upon thispintle are" mounted rollers 8,-9, 10 and 11, the roller; 8 being conical with the end of greatestii} ameter against-the guarthand' the other or smaller eiid abutting the rollers 9. A grains-t the flange 5 is arranged the diskshaped' wheel or roller 11 ofsutlicien-t: diameter toproject well above the others and the ad" 'eiently to allow of the flange .3 being hooked of the tire resting upon either of the rollers lwhichthe device is held as shown,

8 or 9 according to its size, in which position it is retained-and prevented from slippingv back by the roller 11 engaging its inner side and by the downwardangle at in Figs.

1 3 and 6.' When the shoe is then-moved along the rim, therollers 9 and-10 bea' 'fn 'the'flange thereof, the tire will b i tdually "forced from engagement therewn by one upon I or another of the rollers and. fall upon the ,outer'side of the flange in rear of the device as it travels, until the entire circumference has been traversed, the. roller 11 preventingit from slipping back by engaging the inner surface thereof. Th-e outer bead much the same manner, except that the,

' position; When drawn al ong the ri1n, .the bead of the .tire is raised sufficiently. bythe will then be completely disengaged and the. I rest of the tire maybeeasily' removed from the rim the ordinary manner.

To replace the tire, the shoe is inserted in flange or projection 4 is also hooked over the flange of the rim, bringing the edge l t of the'guard. well in toward the tire'- an( lf t he deyice is. held more nearly in a, horizontal- I rollers to clear thelatter, while the guard 2 operates to guide or press it inwardly into proper position behind-the flange of the rim, as shown in Fig. 2. The shoe may then,

by an upward movement, be easily disengaged. The edges of the guard are rounded or, rolled slightly-to preventinjuryto the surface of the tire when in contact there:

with.

In operating. upon;.light .tires a suitable handle (not shown), may be formed upon an extension of the pintle 7 for drawing the devicealong the rim, butthe'larger and heavier ones are morediflicult of.manipula-- tion. I", therefore, provide an. attachment upon the shoe, preferably an eye 15, stamped from'sh'eet material and pivoted to the pro jecting endof the pintle 7, formin a link through which is passed (in adjusta 1e rela-j tion thereto,:a f.ter the. shoe has been put in i place,') the end of a tubular rod 16, the other end of 'which is preferably provided with an eye 17 adapted toeflcircle and bear against the hub 18 of thewheel, as shown in Fig.'1, .and protected -to. "prevent marring the same by a covering ofrubber, leather or other non-abrasing material, though a yoke might answer the purpose or other suitable bearing connectionsmight be made i with 'that or other'portion's of the wheelm In 'ithe-end of thesai'drod is adapted to beiiiiserted a smaller rod 19 serving as a l1andie to. the adjustable lever' thus -:for ii;e ,j aving its fulcrum upon the hub of'the wheel, "itvhereby' thei'slioe maybe drawn along the rim ii ithcomparative ease. 'jrThe are *1 permitted, of course, to projectout.

against rotation during the operation, as

shown in Fig. 1. The end of the rod may also be; flattened for use in inserting the shoe beneath the tire in the first instance, as before described. t Adevice of this nature embodying my i vention .eanbe made light and st-gong at small cost; of manufacture, yet of a SIZG whereby it may be conveniently carried in a tool kit or packed within a small space, the adjustable features of the lever'and its sliding connection with the shoe making the one device applicable to tires and wheels of all sizesand' operable in spite ofthe otherwise unfavorable proximity of mud guards or othe'radjacent obstructions. By its use alargejalmount of timecan be saved in an' are frequentlycalled upon to accomplish while the labor attendant thereto is greatly reduced. 1 1 I claim asm'y invention:
